OD turning with an endmill in a boring head.

[@JanBinnendijk]

Used this trick myself.. for machining a precise boss on a part once.. but i used a standard boring cutter instead.. worked like a charm..

[@southerningenuity4458]

Very cool. I had to use an end mill in my boring head too one time. I thought I was the only one.

[@ellieprice3396]

Good job exactly the way I would have done it. Of course you could have used a boring bar but the end mill was a nice change. You obviously needed a different fitting from stock. Nice welding job also.

Creative use of the countersink tool. I have to say, those parallels sticking up a bit would’ve made me jumpy.

Not thought to use end mill or countersink in boring head , will do now , thanks

Bottom line is that you cut off the threaded part. Which could have been done on a bandsaw. But without the chamfer.

[@franksfabmachine7448]

Yes, but the threads would still be there. The need to be removed to weld on another fitting.

[@mehapgood]

Yeah, I’m with @bobengelhardt856. You removed the threaded part with a boring part in a multi-step process. You could have simply cut it off with a bandsaw, or a cutoff wheel,more even just milled it off. The threads would be gone in the same fashion they are gone after your process. Since the chamfer was simply for better welding strength, that could have been done roughly with a grinder too.

@@mehapgoodI have to agree. I’ve done plenty of OD “boring”, even though I have CNC, just for the roundness aspect of it. But none of the boss was left behind. Why not just mill it off?

[@bradchristy8429]

Sooo…. Why not just mill it off?
